FGO - thrilling immortal team gameplay 5

Turns out this quest is 100% immortal team-able. The actual hard part is that you need to have all 3 pieces of the immortal team yourself. No relying on a friend support for that because you're forced to pick the ultra useless Karna as support. I remember trying to clear the quest back last year and I had no Merlin back then to immortal team and I couldn't figure out a comp to beat him. Turns out I did have a comp that worked, just not one that did it super consistently. I could've used Euryale to obliterate Arjuna. I think I did try that, but after the third time Arjuna killed Euryale, I just kinda gave up and used a Leyline Stone. Getting Euryale to do back-to-back NPs is a pain in the ass. Team: Himiko NP1 L90 10/10/10 with Magical Girl of Sapphire Castoria NP1 L90 10/10/10 with Magical Girl of Sapphire Merlin NP1 L90 10/10/10 with Magical Girl of Sapphire Everyone else is there for bond or is the forced Karna support I gave everyone Magical Girl of Sapphire because the NP Gain is really needed against this Berserker boss. I think Prisma Cosmos would also work well. I went with the Himiko version for a little extra safety than the Morgan version would offer. You really do not want to take a single hit from Arjuna Alter because he can easily oneshot you. The Morgan version can sometimes take a real hit if you have some bad luck. Here, you'd need exceptional bad luck for Arjuna to hit you. The Reines version is probably even safer. I think you'd still take a hit once or twice, but you'd have an easier time getting NPs and removing the Berserker defensive disadvantage is very useful. Only issue is that it would take even longer than the Morgan/Himiko versions.
